Do you know about Tsunami Flags?
A tsunami flag* is a red and white flag used to warn people that "a tsunami might be coming" or "a tsunami is coming."
They are used at beaches (places where people swim in the ocean) and areas near the sea.
A tsunami is a large, fast-moving wave that occurs when there is an earthquake under the ocean or similar events.
